THE SCREEN DISPLAYS
TEMPERATURE LOWER THAN 89.6°F (32°C):
To take the surface temperature, press the Mode button and set the reading to “Body.”
If the device is set to the “Surface Temp” mode, the 89.6°F (32°C) temperature
displayed is showing the external temperature of your body, rather than the internal.
QUESTIONABLE MEASUREMENTS OR IMPROBABLE DISPARITY BETWEEN SUBJECTS
Be sure to avoid any drafts (from nasal specs, air conditioning, etc…). Allow a 1 minute
interval between measurements and be sure to let device acclimate for 10-15 minutes
to significant changes in ambient temperature.
THE SCREEN DISPLAYS THE MESSAGE
HI
When using the Non-Contact Professional Thermometer, the message HI can show on the
screen. In this case, the temperature reading is above the measurement range selected,
either above 109°F (42.9°C) in “Body” mode or above 244.4°F (118°C) in “Surface Temp”
mode.
THE SCREEN DISPLAYS THE MESSAGE
LO
When using the Non-Contact Professional Thermometer, the message LO can show on the
screen. In this case, the temperature analyzed is under the measuring range selected, either
less than 90°F (32°C) in “Body” mode or less than 32°F (0°C) in “Surface Temp” mode.
This message displays for various reasons. Please find below a list of the main issues:
Reasons for LO message display
Advice
Temperature reading hampered by hair
or perspiration.
Make sure there is no obstruction or
dampness prior to taking temperature.
Temperature hampered by an air draft or
dramatic change in ambient
temperature.
Make sure there is no air blowing in the
area of use; this could affect the
infrared reading.
Temperature readings are too close together,
and the thermometer did not have time to
reboot.
If LO message persists, pause for a minimum
of 15 seconds between readings; a one-
minute pause is recommended.
The measuring distance is too wide.
Use target finder LEDs until there is a single
point of light on the patient’s forehead, the
recommended measurement distance is
2 in (5 cm).
